Title: Scanning system
Inventor: POUYA FIROUZ
IPC: G01N21/89
Filed: 1989-10-17
Abstract: A scanning system is for detecting articles e.g. eggs 11 on a conveyor 10. Eggs 11 pass below a light source 14 and light from the eggs 11 is reflected to a video camera 15. The video camera 15 scans the conveyor transverse to its direction of movement 13 a plurality of times within each of a series of bands spaced a predetermined distance apart. The band width has to be sufficiently wide to distinguish gaps between touching eggs 11 and narrow enough to minimise the chances of rescanning the same egg 11 within the previous band or the next band. The scanning system may be used in an egg counter. Alternatively, it may be used to detect holes in sheets in a laundry. <IMAGE>

Title: Security device for standpipes and underground stop valves
Inventor: WIGLEY ALBERT FLETCHER
IPC: E03B9/10
Filed: 1989-12-30
Abstract: In Figures 1-3 an underground stopvalve (10) for general purposes or service stopvalve for standpipes has an extended spindle (15) with a protective casing (12) secured to the valve and terminates above ground with a padlock cap (18) protecting the operating lever (16). In Figure 4 a lockable control valve (10) connected to a double check valve (32) and vertical standpipe (34) has an elbow discharge outlet and Figure 5 is a short version of the valve unit with a hose union bib tap (42). Both units Figures 4 and 5 are for temporary use, and removed for checking the efficiency of the check valves. Standpipes with service stopvalves (Figures 8-7) have supply pipes and checkvalves connected to control valves surrounded by insulation within a metal casing with the valve spindles operated by an external crutch and cap. When installed in extreme frost conditions compressed air can be injected through a test plug within a lockable cap and with the plug connected to a tube and union nut at the base of the supply pipe, water can be expelled from the pipe system. All standpipes (Figures 1-12) have an air chamber and air circulating apertures through an upper cover of the chamber and around the insulation. <IMAGE>

Title: Scanning probe microscope
Inventor: KARRAU KHALED
IPC: H01J37/28
Filed: 1994-05-11
Abstract: The microscope comprises a tip piece which is attached to an oscillator of piezoelectric material. This oscillator is coupled to a further oscillator thereby forming a coupled oscillator arrangement. In a most preferred embodiment, the coupled oscillator arrangement is a quartz piezoelectric tuning fork. In use, the tip piece is vibrated relative to the sample. Tip-sample interaction strains the piezoelectric material and is measurable via contacts placed on the piezoelectric material which are responsive to the strain-induced piezoelectric charge. The coupled oscillator arrangement allows large Q of several thousand or more to be realised. The microscope is easy to operate due to the purely electrical signal collection. The probe head can operate in vacuum, at cryogenic temperatures or in high magnetic fields. <IMAGE>

Title: Gas turbine engine axial thrust balancing
Inventor: HARAMURA SHIGENORI
IPC: F02C7/06
Filed: 1995-03-17
Abstract: A gas turbine engine comprises turbine 3 and compressor 4 elements on a rotary shaft 2. The shaft 2 is rotably mounted on pre-loaded axial thrust bearings 1a, 1b. As it rotates in use the turbine 3 and compressor 4 elements create an axial thrust load F on the bearings 1a, 1b. According to the invention that axial thrust load F is opposed by an electromagnetic coil 12 which is energized to exert an axial force on the shaft 2 in opposition to the axial thrust load F and preferably completely balancing the axial thrust load F. Bearing life is much extended. The axial position of the shaft 2 is detected as the compressor tip clearance by position sensor 13 and the position is compared with a set point value 15 in comparator 14. An error signal is used to supply a current to coil 12 to oppose the axial thrust.
